EMBODIMENT OF THE INVENTION Hereinafter, a gas cooker according to an embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1, the flange at the tip 7 of the cylindrical part 7a of the burner head 7 and the juice pan 11 are joined by welding, and the thermocouple 3 and spark plug 4 are held between the lower part of the burner door and the juice pan 11. The mounting bracket 12 is fixed by welding or pressing.

As shown in the partial view of Fig. 2, the mounting bracket 12 is provided with through holes A and A' and one hole in the upper and lower parts. It is fixed by screws or welding. A thermocouple 3 is provided with circumferential grooves d and d' in a part of the square circle from below the juice pan 11 on the mounting bracket 12.
1 Insert the spark plug 4 into the upper and lower through-holes A and A'0 of the bracket 12.

The thermocouple 3 and the spark plug 4 are positioned in the horizontal direction by the opening, and the plate spring 13 press-fitted into the grooves d and d' of the thermocouple 3 and the spark plug 4 are used to position the thermocouple 3 and the spark plug 4 in the vertical direction. We try to maintain the following.

As a result, the positional relationship between the thermocouple 3 and the burner head door is maintained at a fixed position, and the flame of the burner always hits the appropriate position, thereby preventing the problem of not maintaining ignition due to insufficient thermoelectromotive force. The suhana cassock 8 shown in FIG. 1 is constructed so that it can be attached and detached by simply fitting it into the burner. Further, a mounting foot 14 for attaching to the main body 1 of the device is provided at the lower part of the soup saucer 11.
